About the 0W1 Code Range

The ICD-10-PCS root operation Bypass (Code 0W1) in the Medical and Surgical section involves creating an alternate route for the flow of fluids, usually to circumvent an area of blockage or damage within anatomical regions. It establishes a connection between two separate body cavities or sites, often using a synthetic substitute.

This root operation is commonly applied to body parts such as the Cranial Cavity, Right and Left Pleural Cavities, Peritoneal Cavity, and Pelvic Cavity. The codes specify different bypass routes, for example, from the Cranial Cavity to the Right Pleural Cavity (0W110J9) or from the Peritoneal Cavity to the Bladder (0W1G0J6). Approaches include Open, Percutaneous, and Percutaneous Endoscopic, reflecting the invasiveness and technique used. Utilizing a synthetic substitute is a frequent component of these procedures, facilitating durable and effective bypasses. Detailed coding under this root operation ensures precise documentation of the bypass location, method, and material applied, critical for clinical records and billing.

Questions About This Page

How many billable codes are in the 0W1 range?

Of the 92 codes in this range, 91 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.

What does the 0W1 range classify?

The range classifies Bypass procedures, altering the route of passage of the contents of a tubular body part, performed on the anatomical regions, general. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
